I don't see the bubble bursting anytime soon, at least not in the GTA.
The key reason why the GTA is absurdly going up in value really comes down to a handful of factors:
- Super low mortgage rates. Everyone should be paying somewhere around 2.00 - 2.50%. But even if you locked in at 3.00% that's still a great deal
- Tons of people moving into the GTA. What's the net change every year? Something like +100k? That's a lot
- Most new developments are condos. Great for starters or single people, BUT...... the key reason why homes are zooming is because some people don't want to live in a condo. That's fine, but there's not many detached homes being built unless you want to live an hour out of town. So you have to pay up. That sketchy home with 60 year pipes, faulty wiring, a basement where every 6ft guy bangs their head on the ceiling, and looks like has never got a fresh coat of paint, is probably worth 5x what it was 20 years ago because some people have to have a yard and driveway. That's fine. But it's a sellers market. You want that front and backyard and want to still live reasonably close to the Toronto hub? Well, then pay up. Or, move to a modestly priced home..... 40 km away
The biggest bubble burster is if somehow mortgage rates creep up to let's say 4.00-5.00%. A 2.00% difference vs. current rates doesn't sound like a lot, but homes are worth so much now with people having big mortgages that a $500,000 mortgage at 2.00% more is a lot of extra costs. Some people won't be able to carry the load. That's where it would fall. But for the past 6 years, interests rates have FALLEN.
